AirVac DRS-27T

Features/Benefits:

Repeatable Thermal Performance
Closed-Loop Temperature + Flow Rate = Total Closed-Loop Heating

UPPER HEATER:
• 2000 watt high efficiency (patented) with PID control
• Integrated cool air bypass reduces package temperature and controls joint
• time over reflow.
• Mass flow controller regulates precise heat flow (accuracy and linearity
• +/-1% repeatability , .1% full scale).
• Calibration controls for temperature and flow rate at multiple set points.
• Thermocouple-based stabilization takes in to account the thermal mass of
• the heating system to refine heat output to component.

BOTTOM HEATER:
• Radiant IR panel bottom heater (high thermal uniformity), based on black
• ceramic high emissivity coating, dramatically increasing radiant energy.
• Preheat of board is temperature-based via IR temperature sensor of
• thermocouple
• Integrated automatic pcb and machine cooldown system; insures operator
• safety handling pcb, brings system back to initial conditions for process
• repeatability and aids in controlling joint time over reflow.
• Integrated pop-up pcb supports, pcb expansion control, and flexible
• position pcb edge supports

Multiple Field of View Vision System
Provides Enhanced, Accurate, Quick & Easy Viewing
• Field of view: 70mm; 125mm (optional)
• Nine (9) position viewing; four (4) corners, four (4) sides, and center
• High magnification is programmable or operator adjustable to enhance
• placement accuracy and to minimize operator interpretation. Motorized
• joystick control for quick and easy adjustment.
• Independent intensity for component (green) and board (white) to provide
• clear, fast, and accurate alignment

Closed-Loop Automation
Promotes Simple, Fast, Non-Operator Dependent Process Control
• Force placement control: load cell indicates actual (real-time) and target
• setting (20-2000 grams).
• Programmed z and vision axis: component placement, pickup, flux/solder
• dipping and drop off.
• Motorized joystick theta and z axis control for quick and easy component
• alignment
• Vacuum sensor control: activates automatic component removal
• (eliminating solder squeeze out) and to monitor/maintain non-contact
• tip height for site cleaning.
• Temperature-based preheat: regardless of machine or board conditions,
• the non-contact IR sensor triggers when preheat setting is reached and
• monitors throughout the process.
• Modular software enables rapid implementation of complex motion, vision
• and process controls.

Proprietary Site Cleaning
Non-contact vacuum removal
• Vacuum sensor automatically and continually adjusts tip height and
• compensates for variable residue solder volume.
• Closed-loop hot gas heats pads after component is removed.
• Non-abrasive, composite vacuum tip safely removes residual solder.
• Eliminates damage to pads and solder mask caused by contact-based
• methods.
• Micro components utilize micro contact tips without affecting adjacent
• dense area.

Custom Nozzle Design
Engineering design is critical to thermal process control
• Standard nozzles for conventional components
• Special nozzles for special attention to thermal control, joint temperature
• uniformity, limitation of heat to device or sensitive areas and production
• concerns. Air-Vac has designed and manufactured thousands of nozzles for
• BGA's, 01005's, connectors, QFN's, sockets, and more.

Auto Profiling Software
Automatic, easy one pass thermal profiling
• Simply set the target temperature and go.
• Preheat, soak, ramp, reflow, and cool down events are automatically run.
• After the profile is complete, then entire rework process (removal, site
• cleaning, replacement) is built automatically and ready to run.

Life of Equipment Support
Free phone support and software upgrades
• Our ongoing technical service and process support is a major
• value-added part of our total product offering.
